This is the only building left on the site and I cannot be sure that I can identify it from contemporary photos - though no doubt locals do know what it was. There is one riveted iron vessel there too, not a pressure vessel. There is local interest in moving this pressure vessel down to near the highway where visitors/travelers can see it. I would not endorse that unless a decent storyboard was erected by it to direct people to see where it came from. New Zealand's heritage artifact protection legislation does not apply to this industrial site which could be argued may be post 1900.
